What is the normal range for GFR?
What is the normal range for GFR?
A GFR of 60 or higher is in the normal range. A GFR below 60 may mean kidney disease. A GFR of 15 or lower may mean kidney failure.
What leads to an increase in GFR?
Increased blood volume and increased blood pressure will increase GFR. Constriction in the afferent arterioles going into the glomerulus and dilation of the efferent arterioles coming out of the glomerulus will decrease GFR.
What is stage GFR?
Stage 1 with normal or high GFR (GFR > 90 mL/min) Stage 2 Mild CKD (GFR = 60-89 mL/min) Stage 3A Moderate CKD (GFR = 45-59 mL/min) Stage 3B Moderate CKD (GFR = 30-44 mL/min) Stage 4 Severe CKD (GFR = 15-29 mL/min)
What is a normal GFR for a 60 year old man?
Age 40-49: 99 mL/min/1.73 m. Age 50-59: 93 mL/min/1.73 m. Age 60-69: 85 mL/min/1.73 m.
What causes the GFR to decrease?
A decrease or decline in the GFR implies progression of underlying kidney disease or the occurrence of a superimposed insult to the kidneys. This is most commonly due to problems such as dehydration and volume loss. An improvement in the GFR may indicate that the kidneys are recovering some of their function.
How is GFR related to blood pressure?
Hypertension is one of the most important causes of end-stage renal disease, but it is unclear whether elevated blood pressure (BP) also accelerates the gradual decline in the glomerular filtration rate (GFR) seen in the general population with increasing age.
What is your GFR and why is it important?
Your glomerular filtration rate (GFR)–considered by medical professionals to be the best measure of kidney function–lets kidney care experts figure out your stage of kidney disease. Understanding it can help you learn how to take control and make any change to certain lifestyle habits in order to possibly slow the progression of your condition.
What does a GFR level of 89 mean in CKD?
Kidney damage and mild decrease in GFR. GFR LEVEL: 60 TO 89 mL/min. In Stage 2 CKD, the GFR is mildly decreased between 60-89, indicating the person has kidney damage and mild loss of kidney function.
What does it mean when your GFR is 45?
Your kidney function is still considered normal if the GFR number is 90 or greater. If your GFR is 45, you know that your kidneys are working at approximately 45 percent of the normal rate. Stage 1 Kidney Disease Healthy kidneys or kidney damage with normal or high GFR
What does a GFR of 100 mean on a blood test?
What Your GFR Result Means Completely healthy kidney function is measured at a glomerular filtration rate (GFR) of around 100, which means that the kidneys are working at 100 percent. Your kidney function is still considered normal if the GFR number is 90 or greater.
